Solid SQLite3 REPL (C++)

Features:

• Core REPL with .exit
• Meta commands: .tables, .schema, .help, .run, .export, .refresh
• Fish-like inline suggestions (ghost text) implemented in a simple LineEditor
• Script execution: .run file.sql
• Query profiling: execution time after each query

Build:

• Requires SQLite3 dev library and CMake
• mkdir build && cd build
• cmake .. && make
• ./sqlite_repl

Notes:

• This project aims to be a practical foundation. Replace the LineEditor with a more robust line-editing library (replxx, linenoise-ng) for full-featured UX.
• CompletionEngine uses a schema provider to fetch tables/columns; refreshSchema rebuilds caches (called by .refresh). It now uses token-based context analysis for more robust suggestions.
